Wireless Communication Thesis for PhD Research Scholars.
Wireless communication thesis provide effective tool for easy use and it has replaced fax, WAP, Morse code and telex. The information or data send from source node and received by destination node by analog and digital format is communication. Wireless communication thesis plays a vital role in information exchanged system projects. Wireless communication thesis is submitted by communication researchers related to networking with optical communication and wireless communication.
Wireless Communication Thesis Topics:
Data interaction processes with photons are performed under optical communication. Photonics is referred as study of processing, controlling and generating photons. Fiber optic cable acts as communication medium in optimal communication. Long and thin core that are covered by pure glass of cladding with fiber optic jackets are contained in fiber optical cable. Long distance communication use fiber optic cable. It guides the light from one end to the other for data transmission. Data under fiber optic communication are sending in form of light in fiber cable.
Advantages of fiber optic communication:
- Size is very small.
- High bandwidth.
- For long distance communication data can be transmitted.
- Attenuation is low.
- Low security risk.
- There is no interference occur.
Optical fiber communication components:
- Digital signal processing.
- Optical media.
- Electrical to optical transducers.
- Optical to electrical transducers.
Fiber optic transmission limitations:
- Dispersion and attenuation are suffered by fiber optic transmission.
- Bandwidth distance products are created by dispersion.
- In multi mode fiber cable, multi mode dispersion and chromatic dispersion occur.
- At various speed pulse spreading travel to reduce the communication performance.
Some limitations are faced under fiber optic communications and must be overcome. Communication Engineers workout for faster date rate mechanism, more sophisticated network architectures for reducing cost, traffic and time.
Optical fiber types: On basis of refractive index and propagation fiber optic cable are clarified. Classifications of propagation are single mode and multimode basis of refractive index in optical fiber are categorized as graded index fiber and step index fiber.
Multi mode fiber: Various types of cable properties are contained in multimode fiber.
- Graded Index.
- Step index.
Single mode: A core diameter is contained in single node fiber cable which is equal to wave length of emitted light.
Fiber optic working frequency: Fiber optic cable frequency range is categorized on transmission data distance equal to time. There are:
O-band: O denotes original and frequency range from 1260-1360nm.
S-band: It starts from 1440-1530nm.
E-band: It is referred as extended band frequency range from 1360-1440nm.
C-band: Conventional band starts from 1530-1565nm.
L-band: L denotes long band frequency range (i.e.) 1565-1625nm.
U-band: Ultra long uses frequency range is from 1625-1675nm.
